This study was performed in order to determine the relative and combined effects of ethanol, a low protein diet and steroid treatment on bone, muscle, liver, and urinary and faecal excretion of zinc, copper and iron in 64 rats divided into eight groups treated following the Lieber-DeCarli liquid diet technique, with and without dexamethasone, 1 mg/l. Steroids showed a lack of effect on liver zi...

Tobacco (Nicotiana tabacum L.) is a commercial plant. Tobacco leaves naturally accumulate and concentrate relatively high levels of heavy metals and particular cadmium in leaves. Tobacco is one of the basic agricultural products, in Ethiopia, with social and economic importance. However, there is no report in the literature on the determination of levels of heavy metals in Ethiopian tobacco lea...

Wilson’s disease is an inherited defect in biliary copper excretion, causing a buildup of copper and copper toxicity, primarily in liver and brain. Presentation with liver disease and/or neurological disease usually occurs in the second and third decades of life. Recognition of the disease is often delayed, which is unfortunate, because once appropriate treatment is started, progression of the ...

Oxidative damage has been proposed as one of the possible mechanism involved in the nephrotic syndrome. Strengthening the defense system by antioxidants may provide protection against oxidative damage. Therefore, this study was carried out to investigate oxidant and antioxidant status with copper, zinc and homocysteine in nephrotic syndrome patients and the effect of antioxidants, minerals and ...

INTRODUCTION The fitness of water supplies for public consumption may be assured by minimal treatment where high purity sources are available. Aluminium sulphate is used in the coagulation process forming a floc which acts as a filter for the removal of finer particles. The presence of a high concentration of aluminium sulphate in the water supply lowers the pH of the water and may result in th...

Chemical forms of Zn, Ni, Cu, and Pb in municipal sewage sludge were investigated by adding humus soil to sludge and by performing sequential extraction procedures. In the final sludge mixtures, Zn and Ni were mainly found in Fe/Mn oxide-bound (F3) and organic matter/sulfide-bound (F4) forms. For Zn, exchangeable (F1), carbonate-bound (F2), and F3 forms were transformed to F4 and residual forms...

The goal of this study was to determine the removal efficiencies of chromium, copper, lead, nickel, and zinc from raw wastewater by chemically enhanced primary treatment (CEPT) and to attain a total suspended solids removal goal of 80%. Operating parameters and chemical doses were optimized by bench-scale tests. Locally obtained raw wastewater samples were spiked with heavy metal solutions to o...
